Health issues in women midlife linked with health decline at 65


 

FROM JAMA NETWORK OPEN

Having specific health issues, including depressive symptoms and cardiovascular disease, as a middle-aged woman was associated with experiencing clinically important declines in health later in life, a new study finds.

The most predictive parameters of poorer health at age 65 were cardiovascular disease, clinically significant depressive symptoms, and current smoking. Osteoarthritis, lower education level, and higher body mass index (BMI) also were associated with poorer health status 10 years on, Daniel H. Solomon, MD, MPH and colleagues wrote in their observational study, which was published in JAMA Network Open.

Determining a patient’s score on a health-related quality of life measure based on these variables might be useful in clinical practice to recognize midlife patients at increased risk for later health deterioration, Dr. Solomon, of the division of rheumatology, inflammation, and immunity at Brigham and Women’s Hospital, Boston, said in a statement. This measure is called the Short Form 36 (SF-36), and the researchers specifically focused on the physical component summary score (PCS) of this measure. The SF-36 is similar to the Framingham 10-year coronary heart disease risk prediction score, according to Dr. Solomon, who is a professor of medicine at Harvard Medical School, also in Boston.

Based on their risk scores, women could preemptively target modifiable risk factors before they enter old age, the investigators wrote.

“Age 55-65 may be a critical decade. A person’s health and factors during this period may set them on a path for their later adult years,” Dr. Solomon said in a statement. “The good news is that a large proportion of women at midlife are very stable and will not go on to experience declines. But being able to identify women at higher risk could help lead to interventions targeted to them.”

Study details

The study included a cohort of 1,091 women drawn from the 3,302-participant Study of Women’s Health Across the Nation (SWAN), a racially and ethnically diverse group enrolled from six U.S. sites at or immediately before transition to menopause and followed for 10 years from age 55 to 65. The study sample, consisting of 24.6% Black, 24% Japanese or Chinese, and 51.9% White, had a median baseline age of 54.8 years and median BMI of 27 kg/m2 at entry. The median baseline PCS score was 53.1 (interquartile range, 46.8-56.7).

Over 10 years, 206 (18.9%) of the women in the study experienced clinically important declines of at least 8 points in baseline characteristics at around age 55. The following were significantly associated with these declines:

  • Having a higher BMI.
  • Having osteoarthritis.
  • Having a lower educational level.
  • Being a current smoker.
  • Having clinically significant depressive symptoms.
  • Having cardiovascular disease.
  • Having better (or higher) physical health and function score on the PCS.

The association between a higher PCS score and a greater decline might seem like an anomaly, Dr. Solomon said in an interview, but one interpretation of this finding is that women with higher or better scores at baseline have further to fall once other risk factors take effect.

With data analyzed from October 2020 to March 2021, the median 10-year change in PCS was –1.02 points, but 206 women experienced declines of 8 points or more.

Those with health declines were more likely to be Black and less likely to be Japanese. They were also more likely to have other comorbidities such as diabetes, hypertension, and osteoporosis, and to report less physical activity.
